Technical Field

Background
The pulse welding is that the material to be welded is pressed between two heating elements, and a strong current is introduced to make the heating element produce strong pulse of heat energy in a very short time, and then the heating element is cooled, at the moment, the welding surface is fused under the condition of heating and pressurizing. In the welding process, the process of igniting the electric arc by the welding material is called arc ignition. The success rate and stability of arc striking of both manual welding and automatic welding are very critical, and are directly related to the quality of welding seams of products. The arc striking is also a part with high occurrence of welding defects, and if the arc striking is not stable enough, the defects of wire breakage during welding, large welding spatter, poor welding seam fusion effect and the like can often occur. These defects are hidden from view in the case of welds which involve covering the arc ignition point.
The second welding parameter shape of conventional pulse welding arc initiation control is the same as the main weld. This may in some cases lead to unstable arc during the arc strike stage, due to inappropriate second welding parameters for certain wire feed quantities, etc., or to an arc strike that is not smooth due to inappropriate energy matching.

Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
As shown in fig. 1, an embodiment of the present invention provides a pulse welding control method, including the following steps:
s100: acquiring a preset first welding parameter at the beginning of a climbing stage and a preset first welding parameter at the end of climbing;
s200: determining second welding parameters at various moments in the climbing stage according to corresponding relations among preset first welding parameters at the beginning of the preset climbing stage, the preset first welding parameters at the end of climbing and the second welding parameters in the climbing stage;
s300: and controlling the welding pulse output in the climbing stage according to the second welding parameter at each moment in the climbing stage.
Therefore, the second welding parameters in the arc striking and climbing stage are reset in the step S200, and the second welding parameters different from those in the main welding stage are adopted in the arc striking and climbing stage, so that the perfect matching of the welding energy and the wire feeding speed is realized, the stable arc striking is realized, the smooth transition of molten drops in the arc striking stage is controlled, and the defect in the arc striking stage is avoided.
Specifically, the second welding parameter adjusted in the climbing stage may be a pulse frequency change to achieve perfect matching between the welding energy and the wire feeding speed, or may be a pulse frequency change to achieve perfect matching between the welding energy and the wire feeding speed by changing other second welding parameters, such as at least one of pulse parameters of a peak current, a base current, a second base current, and a pulse time, so as to control smooth transition of the droplet in the arc striking stage. The perfect matching of the welding energy and the wire feed speed can also be realized by changing at least one of the peak current, the base current, the second base current and the pulse parameters in the pulse time while changing the pulse frequency. When different materials are welded, due to the fact that the physical properties of the different materials are different, the corresponding pulse waveform and the control mode can be adjusted during arc striking, and therefore the smoothness and the stability of arc striking are guaranteed.
Further, in order to ensure the smooth transition from the climbing stage to the main welding stage, when the main welding wire feeding speed is reached, the pulse waveform at the end of the climbing process is adopted to maintain for a period of time t. Specifically, the step S300: after the welding pulse output by the climbing stage is controlled according to the second welding parameter at each moment in the climbing stage, the method further comprises the following steps:

The welding mainly comprises four stages: part of the welding process is a slow wire feeding stage, part of the welding process is a climbing stage, part of the welding process is a transition stage, the transition time is t, and the welding process is a main welding stage. When the welding wire contacts with the workpiece, a first arc striking pulse is output, the first arc striking pulse corresponds to a slow wire feeding stage, and the wire feeding speed maintains a slow wire feeding speed V Slow . And entering an arc striking and slope climbing stage after the first arc striking pulse is ended, wherein special pulse waveforms and control are adopted in the process. In the climbing stage, the wire feeding speed is changed from a slow wire feeding speed V Slow To main welding speed V Main The increase is made at a given acceleration a.

In the present invention, since the wire feeding speed at the beginning of the climbing stage is the same as the wire feeding speed in the slow wire feeding stage, the same mark V is used Slow And (4) showing. Since the wire feed speed at the end of the hill climbing phase is the same as the wire feed speed in the main welding phase, the same sign V is used Master and slave And (4) showing.

X 1 Can be adjusted as desired, for example, according to different V Master and slave Different first adjustment factors are set. In this embodiment, before determining the second welding parameter at each time in the climbing stage according to the following formula, the following steps may be further included:
according to a preset first adjusting coefficient and the wire feeding speed V at the end of the climbing stage Master and slave Setting a first adjusting coefficient according to the corresponding relation.

In the transition phase (c-c), the pulse frequency F at the node (c) is still used n Until the main welding stage is reached, the pulse frequency is set to the set pulse frequency F of the main welding stage Master and slave 。
Fig. 3 is a schematic diagram of a pulse welding control method according to another embodiment of the present invention. In fig. 3, the upper half represents the change in wire feed speed with time, and the lower half represents the change in welding current with time. The welding mainly comprises four stages: part I, part II, part III, part IV, part V, part V, transition time T, and the last main welding stage.
